You should have options with Toyo R888 and Hoosier...
Thanks,Dr. DesignD3 Cadillac

Doc, what sizes do you run in 19" on the Sedan? I see nothing close to the 27" OD. And the oem size does not seem available in Hoosier or Toyo R compound. Or am I missing something ??? I'd like to get a set of OEM rims, and just run R compounds.

Unfortunately there is no 27" OD available. we had to work with what the tire manufacture had to offer, There's definitely not a lot of options but the good news is that we have tested different tire and wheel set up at the track and We have had very good luck with these set up:

Sedan and Wagons
Square Set Up:
19x9.5 with 295/30R19 Toyo R888 all around ( we basically took the factory rears wheels and ran our D3 hub centric spacers and extended stud kit for offset correction)

Years ago, when I was running auto-x on a competitive level, they wanted their stickers on my car. I'm sure they would want their tires on a V. They may not even know what a V is, but once they know, hey, you never know what can happen. I do know, if you don't ask, it'll never happen.

Have you tried 305/30/19 on the back and 295/30/19 on the front on a sedan? The rears will be .5in taller and a bit wider and of course a wider rim will be needed for the rear. Will this setup need a speedo re-calibration?

Thank you

We have tried a 305/30R19 Toyo R888 and ran into some rubbing issue with using a Widened 19x10.5 factory CTSV wheels and we have also tried running a 305/30R19 Bridgestone RE11 on the same exact wheels with NO rubbing issues what so ever. It all depends on tire manufacture you are running, believe it or not even though they both say 305/30R19 on the side wall they are completely different widths. As far as the speedo recalibration most of the guys do not even bother to do it because it is also their daily driven vehicles and they install their normal 27" OD tire off the track. Recalibration is available if customer wants to do so.

So, I finally had some time to go up to Brainerd Interenational Raceway (BIR). I was instructing at a club event for the day, so I had limited track time.

Here are my impressions of the Vagon.

The Performance Friction 08 brake pads, Motul RBF600 and Grand Am scrubs proved to be an awesome combination. The brake pads were flawless - tons of initial bite, very linear to modulate, great release characteristics and absolutely no fade. I've used PFC pads for years on my race car, and they didn't let me down in my (very heavy) street car. The Grand Am scrubs gave me plenty of grip and were perfect for a DE day - cheap and sticky enough.

Two issues came up... the rear diff overheated with 9 mins of hard track driving, so my sessions were short - very short. If I ever track the Vagon again, a diff cooler is mandatory.

Before heading to the track, I forgot to put aluminum foil over my wheel weights. The front brakes generated so much heat that it melted the adhesive on the wheel weights. When a wheel weight comes off on the track, you hear a disturbing clunking sound and then everything starts vibrating - not fun and confidence inspiring. Anyway, foil taping wheel weights is another mandatory.

Overall, my lap times were 5 sec off the pace of my purpose built #1500 lighter race car. In comparing AIM data, top end speed is faster in the V, but corner speeds are like I'm parking the car in comparison. Yes, it's a heavy heavy heavy vehicle.

It's a fun recreational track car. It certainly doesn't handle like a Corvette. I love it for HPDE's. Then I love driving it home. I wouldn't race it in stock trim.

Here is a video of my buddy in his R8 at Sonoma a couple weeks back. Im the red V he is chasing...! Needless to say even with really worn Hankook RS-3's and luck..lol...he never could catch me. Fun track and slick when warm. Good luck on the track guys
